    I just called for a price on a water to water 5 ton geo unit. The prices came in at $1,200 more for a unit with a loop side pump and expansion tank and $1,600 more for a loop and load system both sides have expansion tanks. These are my cost amounts over what I paid for a "non-pump added" system in January.

    This bothers me a great deal.

    I have for years been scorned for doing what the manufacturer is doing for me at a 300% mark up of my cost to do the same thing. I have always treated the water side of a geothermal heat pump as a hydronics system, with all the bells a whistles.

    I applaud the manufacturer for seeing the light on what their equipment is becoming a part of, but how do they "know" what I am hooking "their" pump to. Do I use 150 ft per ton or 500 ft per ton? What do I have on the load side? How would they know?

    I got this info in a voice mail so I do not know if I can pick the pumps.

    Hey Mark,
    I ran into this with the climate master outdoor units. I simply put a disclaimer in my contract that states the hvac is now responsible for the fluid engineering on the loop side. I had the same questions as you.

    On another note I have a guy im my OA that wants to explore geothermal heating and cooling for a greenhouse operation via e-mail with someone who knows alot more than me about the load side of things. any volunteers?

    Greenhouses

    I've done design work for these. It is a tough sell sometimes as they need to know their crop demands. And those crops often demand excess CO2, which geo is poor at.

    There is a thin line.

    For using geo for greenhouses. Just like Curt says. I do not hold out much hope for a good economic fit, but could look at his situation. Have him call me.
